Tremec 3650 Overview

Since the beginning the 2001 Bullitt owners complained about the transmission not wanting to shift into second gear when cold. In 2004 Ford came out with TSB 04-15-6 which replaced some internal parts and it also quoted a new fill level of 3 liters, (or 3.2 quarts)

I have experimented with about 8 different types of fluid and even the addition of Lucas Transmission Fix.

Recently I noticed where Amsoil's ATF fluid had new lower viscosity numbers than when I had tried it about 6 years ago. I recently serviced the transmission using the new Amsoil ATF fluid and I am very happy to say that this is the best that I have tried so far.
